BINDER HITCH.

Application filed September 30, 1920. Seriallto. 413,74-6.

To all whom it may concern:

Be it known that I, Orro HANSON, a citizen of the United States,residing at Verdi, in the county of Lincoln and State of Minnesota, haveinvented certain new and useful Improvements in Binder Hitches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to certain new and useful improvements in draftconnector for a binder and has for its primary object the provision of asimple form of draft connector for connecting the binder with a tractor.

The invention has for another object the provision of a draft connectorof the character stated which will be constructed in such a manner thatit may be readily converted into a left hand draft connector for a sidebinder or varied to connect a right hand binder with the tractor.

The invention has for a further object the provision of a draftconnector of the character stated which will be constructed in such amanner that the main portion of the draft or strain will be directed tothe longitudinal center of the draw bar of a tractor when either a leftside or a right hand side binder is connected thereto.

The invention has for a further object the provision of a draftconnector of the character stated which will be of simple and durableconstruction and which may be readily secured in position or adjusted,as required.

With the foregoing and other objects in view as will appear as thedescription proceeds, the invention consists in the novel construction,combination and arrangement of cooperating elements as hereinafter morespecifically set forth, claimed and shown in the accompanying drawingsforming a part of the present application and in which Figure 1 is a topplan view of the draft connector employed for connecting a left sidebinder with the draw bar of a tractor or the like.

Figure 2 is a View similar to Figure 1, showing the draft connector asemployed for connecting a right side binder with the draw bar of thetractor.

Figure 3 is a bottom plan view of the draft connector as employed inFigure 1 of the drawings.

Figure 4 is a side elevation of the draft connector as shown in Figure 1of the drawlngs.

Figure 5 is a detail sectional view on the plane of line 5-5 of Figure1, looking in the direction indicated by the arrows.

Figure 6 is a detail sectional view on the plane of line 66 of Figure 1,looking in the direction indicated by the arrows.

Referring more in detail to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, 1indicates the end of the draw bar of a tractor. The draft connectorwhich will be described in detail is employed for connecting to thetractor draw bar, the draft bar 1, the draft tongue 3 of a side binder,a portion of which is shown in the drawings for the sake ofillustration, and designated by the numeral 4:.

In constructing the draft connector shown in the accompanying drawings,I employ an upper main frame member 5 of substantially U shapedconstruction and preferably formed of a flat metallic bar ofconsiderable so strength, also a lower main frame bar 6, similar to theupper main frame bar 5 but which may have a bight portion which isrelatively narrower than the bight portion of the upper main frame bar5, as shown in the drawings. The bight portions of the main bars and 6are placed transversely across the upper and lower faces respectively ofthe draw bar 1, at the rear end thereof and connected by a plurality ofbolts 7 or the like passed through the frame bars 5 and 6 and throughthe draw bar 1. Suitable nuts 8 are mount ed upon the ends of the bolts7 and the central bolt 7 is preferably of slightly increased length, thepurpose of which will presently appear. The bight portions of the mainframe bars 5 and 6 are separated by the draw bar 1, as will be laterseen by referring to Figure 30f the drawings, while the ends of the bars5 and 6 are brought together and have the rear corner bolts 9 extendedtherethrough and also through the end portions of an arcuate draft bar10, extended across the rear open end of the frame, as shown clearly inthe drawings. It will be noted that the draw bar 10 rests upon the upperfaces of the arms of the upper main frame bar 5. The draw bar 10 has apair of inner openings 11 spaced slightly to either side of thelongitudinal center thereof and adapted to receive the bolt 12 employedfor connecting the rear end of the strain bar 13 thereto, said bolts 12passing through the upwardly offset rear end of the strain bar 13positioned beneath the bar 10. The rear end of the strain bar 13 ismounted on the lower end of the central bolt 7 which serves as a pivotfor the forward end of said strain bar 13 as well as one of the boltsfor securing the upper frame bar and lower frame bar 6 to the lower bar1 of the tractor. The bar 10 is also provided with a pair of outeropening 14 between the openings 11 and the ends of the bar 10 to receivethe forward pivot bolts 15 of the connecting bracket 16 for connectingthe draft tongue 3 of the binder 1-, previously mentioned.

The connecting bracket 16 is composed of an upper bracket member 17 anda lower bracket member 18 in the form of metallic strips. These members17 and 18 have their rear end portions secured respectively upon theupper and lower faces of the draft tongue 3 of the binder 1 by aplurality of bolts 19 extended therethrough and the forward end of theupper plate 17 is downwardly offset, as shown in the drawings andbrought into parallel relation with the lower bracket member 18,immediately forwardly of the binder draft tongue 3, the connecting bolt20 being passed through the bracket members 17 and 18 at this point, asshown in the drawings. llt will be understood that suitable nuts 21 aremounted upon the bolts 19 and 20 to secure the same in proper position.Forwardly of the bolt 20, the lower bracket member 18 is offsetdownwardly to be extended beneath the bar 10. Thepivot bolt 15 isextended through this end of the bracket member 18 and through theforward end of the upper bracket member 17 as well as being passedthrough one of the outer openings 14: of the bar 10. A suitable nut 23is also provided for the lower end of the pivot bolt 15.

By referring to the drawings in connec tion with the foregoingparagraphs, it will be seen that when this draft connector is employedto connect a left side binder with the tractor, the strain bar 13 ismoved over the opening 11 and the pivot bolt 12 secured therethrough.The pivot bolt 15 for the bracket 16 is also passed through the leftopening 1 1 of the bar 10 and through the members 17 and 18 of thebracket 16 to pivot this bracket on the left of the longitudinal centerof the bar 10 and on the left of the transverse center or longitudinalaxis of draw bar 1 of the tractor. When it is desired to connect a rightside binder in place of the left side binder, however, the strain bar 13is swung to the other side and the pivot bolt 12 thereof passed throughthe opening 11 to the right of the longitudinal axis of the draw bar 1and the pivot bolt 15 for the bracket 16 carrying the draft tongue 3 ofthe binder a is passed through the opening 1& of the bar 10 toward theright end of said bar 10. It will therefore be evident that when eithera right side or a left side binder is connected with the bar 10 of thepresent form of draft connector, the strain or draft will be properlydirected to the draw bar 1 of the tractor employed and the binder drawnproperly after the tractor.

While the preferred embodiment of the invention has been shown anddescribed, it will be understood that minor changes in the details ofconstruction and arrangement of parts may be resorted to within thescope of what is claimed without departing from the spirit of theinvention.

l/Vhat is claimed is In a draft device for a tractor, the combination oftwo substantially ill-shaped frames one above the other, the bightportion of one frame engaging the upper face and the bight portion ofthe other frame engaging the lower face ofthe draft lug of a tractor, abolt passing through said bight portions and lug, a strain bar throughwhich said bolt passes, a cross bar, bolts passing through said crossbar and the ends of both of said frames to fasten the frames and crossbar in superposed relation and the frames at an angle to each otherwhereby they will abut opposite sides of said draft lug to rigidify theconnection of the frame thereto, said cross bar having a series ofopenings intermediate said ends of the frame and in a path concentricwith the first mentioned bolt for adjustable attachment of draft meansthereto and independently of the strain bar, and a bolt to pass throughsaid openings selectively to fasten said strain bar to the cross barrelatively to the position of attachment of said draft means.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO HANSON.
